GenZD Zero supports running games using the open-source idTech 1 game engine for iOS, and supports running its "WAD" game files as well as community-developed "MOD" files, all rendered natively using modern technology. It supports several capabilities beyond the original engine, such as modern 3D rendering, widescreen graphics, dynamic lighting, a fully scriptable environment, and much much more.
Please note that GenZD Zero does not include content and they must be provided by you. Please use the Files app to move or copy files to the GenZD folder under "On my iPhone" or "On my iPad".
Configurations called "Launch Configurations" can be created using a base game file as well as additional MOD files (.pk3 and .zip files). A plethora of content developed by the community is available on the web, and almost all "mods" that use the UDMF or WAD formats are supported.
GenZD Zero supports any "WAD"s and "mods", but is limited to 3 launch configurations and supports one touch configuration layout. Upgrading to the full version will unlock unlimited launch configurations and custom touch control layouts.
Additional features:
- Game controller support: PS4, PS5, Xbox One, Nintendo Switch, mFi
- On-screen touch virtual gamepad and virtual keyboard
- Customizable touch controls: Rearrange buttons, change color and size. Support for saving multiple layouts.
- Gyroscope aiming
- Widescreen Metal graphics rendering using MoltenVK
- Add your own game and mod files via the Files app
- Accessibility: Supports VoiceOver and mods that support accessibility
- Local Multiplayer: Host a co-op or deathmatch game, discover hosts running GenZD automatically on the same network and join a game
Best way to play Doom on iOS but it does have an issue with the touchscreen and gyro aim, you can't make micro adjustments in your aim like there's a deadzone and changing both the sensitivity in the settings and gzdoom settings messes with it. If you max out the settings sensitivity and use it as a base for the gzdoom sensitivity it makes the deadzone smaller but it's still present and feels bad to the point I can only play with freelook turned off. Im sure most people play with a controller so it's not huge issue but for people that come from other mobile games like COD Mobile or Delta Force Mobile and know how to play well with the touchscreen and gyro it doesn't feel great. Hopefully the Devs see this and can improve the touchscreen and gyro controls.
Its good but i have one issue

Make a option to disable dragging for all buttons because when im trying to select options and stuff the A button can press multiple times from one push and makes things tedious
So good I bought it twice

In absence of a tip jar I wanted to show my support for such an amazing product. Also, it is nice to have redundancy with my favorite apps since Apple seems to have issues with their approval process these days. Keep up the good work and a big thank you for your patience working with Apple.
Very good

For the free version you guys were very light only three launch configs isn’t that bad tbh you can just remove one if your not that crazy about save data honestly I’m surprised there wasn’t any ads in it
